I personally own this vacuum. One of the things I noticed immediately was how much smarter it is than my Roombas. We tested two generations of Roomba, and frankly, they scuff corners and get stuck under furniture with enough frequency that they were a hassle. Not the case with this RoboRock. Plus, I like the app. The app lets me visually see the map of my home, and allows me to send the vacuum to specific zone(s), or clean certain rooms...all with an intuitive, easy app. I'd buy this one again.  

• Efficient and Intelligent: Clean fast, with no random bumping. Using a dual-gyro system together with motion tracking sensors, cleaning is carried out logically and efficiently in every room. Thirteen types of sensors combine to offer cliff sensing, collision avoidance, mid-clean charging, and minimize the likelihood of entrapment.
• Large battery capacity: A large 5200mAh battery offers 2.5hours of non-stop cleaning. A generous dustbin means even big homes can be cleaned in one go.
• Thorough cleaning: 2000Pa of intense suction pulls dirt easily off hard floors, and drags it from deep inside carpet fibers.
• Vacuum and mop: Vacuum and mop simultaneously for sparklingly clean floors. The mop sucks in water evenly as it cleans, so it cleans without leaving puddles.
• App control: use the Mi Home APP and connect Xiaowa E Series to start, stop, schedule, customize, charge, check accessory status, control movement direction and more. A 2.4GHz Wi-Fi network is required.
